if he can, sort of separate them and say which side are you on on abortion, where are you on taxes, whose budget are we talking about, really try and nail down some of the facts that biden and obama feel were not clear enough and not made clear enough in the presidential debate. >> es that' because the president didn't -- that's because the president didn't make them clear. really didn't answer some of the issues that governor romney threw out. how has the rehearsal for this debate gone and maybe different from the presidential candidates' rehearsal? >> there's been quality time on this one. there's some thought that mr. obama wasn't really committed to his debate preparations. that has not been a problem with this one. biden spent basically a three- day weekend doing debate prep. they've been doing debate trep for paul eyian -- prep for paul ryan. they'll be pretty sharp i expect. >> we talked about congressman ryan, very intelligent and he knows what he's talking about but sometimes his views don't match with the top of the ticket. do we expect joe biden to exploit that? >> yeah.
